MANIFOLDING ATTACHMENT FOB TYPEWRITERS.

Application filed March 2, 1922. Serial No. 540,459.

To all whom it may concern:

Be it known that I, MALCOLM L. Cossrr'r, a citizen of the United States, residing at Alameda, in the county of Alameda and State of California, have invented certain new and useful Improvements in Manifolding Attachments for -Typewriters, ;'of which the following is a specification.

My invention relates to manifolding attachments for typewriters and other typing machines, comprising, essentially, a mani folding ribbon; movable members carrying the ribbon and adapted to place it in and remove it from functional position in the line of type impact; and a suitable frame carrying said members and adapted for ready connection with the platen-carriage of the machine.

One object of my present invention is to provide a simple and effective means for releasably holding the ribbon carrying members against inadvertent or accidental displacement, thereby insuring the position of the ribbon both in and out of use. Another object is to provide simple and effective means foradjusting the ribbon witli respect to its width, when in functional position, in order to present it for use over reference being had to the accompanying drawings, in which-- Fig. 1 is a perspective view of my manifolding attachment. showing -it connected with a bar, which is, as will be later shown, a bar at the back of the platen-carriage of the typewriter.

Fig. 2 is a perspective view of the right hand or operative end of the attachment, looking at it from the side opposite to that of the View point of Fig. 1.

Fig. 3 is a cross section through the concentric turnable arm carrying members, on the line 3-3 of Fig. 3.

Fig. 3* is a longitudinal section, partly in elevation of the same on the line 3--3 of Fig. 3.

Fig. 4 is an end view, enlarged, broken and partlV in section on the line 44: of Fig. 6, showing the attachment connected with the platen-carriage of a typewriter, and showing the manifolding members thrown down to functional position, the dotted lines showing them thrown up when not in use.

Fig. 5 is a 'plan view of the operative end of the attachment.

Fig. 6 is a front view of the platen-carriage, on the line 6-6 of Fig. 7, showing one of the manifolding ribbons brought down for use and another still elevated out of the wa Fig. 7 -1s a top plan view showing both manifolding ribbons'in functional position.

.For the sake of simplicity, I shall first describe the attachment complete and then vpoint out its connection with a typewriter.

Referring first to Figs. 1, 2, 3 and 3, 1-1 are brackets, each having an angularly directed foot 1'. In the upper ends of the brackets is rotatably mounted a rod 2, which, for the sake of constructive practice is a tubular rod as shown. This rod is adapted to be turned on its axis by means of the knob 3 on one end. Fast on the rod 2, are two arms 4, one near each end. Between the arms 4 is carried a manifolding ribbon 5, which is omitted from Fig. l, but is shown in Figs. 6 and 7. Rotatabl fitted upon the rod 2 is a sleeve 6, to whic at each end is made fast an arm 7. Between the pair of arms 7 is carried another manifoldin ribbon 8, shown in Figs. 6 and 7. The ribon-carrying arms 4 and 7 at each end preferably overlie each other, the arms 4 being uppermost. A thumb-piece 7' is secured to that one of the arms 7 which is nearest the knob 3 of the rod 2, the

thumb-piece and the knob being in such'relative position, as seen in Fig. 1, that the respective pairs of arms may be moved up or down either separately or together, by the right hand of the operator.

Freely mounted upon the rod 2, just inside the knob 3 is a lever 9. the other end of which is fitted or yoked u on a cam 10, which. as will be presently escribed is to be secured upon the platen-shaft of the machine. The lever 9 is provided or formed with an angularly directed bar 11, which traverses the plane of movement of the ribbon carrying. arms 4 and 7. The free end of this bar 11 carries or is formed with a controlling plate 12. which is formed with a lower resilient tongue 13, and upper resilient tongue 14 and a back stop 15. 7

The bar 11 serves as a stop for the arms 4 and 7 at the lower limit of their movement, while the stop serves to limit their upward movement. The resilient tongues l3 and 14 bear against the edge of the arms 4 and 7, and serve to frictionally hold them against inadvertent displacement in their lower and upper positions respectively.

The parts thus described comprise the I complete attachment.

now be described.

' frame of a typewriter, having a platen-car- Itsfconnection' with the typewriter may 16 indicates part of a riage 17 provided with a back-bar 18. Figs.

4 and 7. 19 is the platen, having a shaft 20 with a knob 21 to turn the platen.

To the back-bar 18 of the platen carriage are secured by the screws 22 the feet 1 of the brackets 1, said brackets thus rising at each end and back of the platen-carriage, the rod 2 and sleeve 6 extending back of and parallel with the platen as seenin Figs. 4 and 7.

In connecting the attachment with the machine, the platen-shaft knob 21 is'temporarily removed, and upon the exposed end of the platen-shaft, is slipped the cam 10 which enters the yoked end. of the lever 9. The cam is made fast to the platen-shaft by a screw 23, and then the knob 21 is rep aced on said shaft. .This completes the mounting of. the attachment.

In the out of use positi'on of the mani folding ribbons, they are elevated above the platen, and in this position, they are frictionally held by the pressure of the upper sprin tongue 14 against the carrying arms 4 an 7, said arms being prevented from falling back any farther, by the back stop 15 of the controlling plate 12. When one of the manifolding ribbons is to be used, the operator, taking hold of the rod-knob 3 between his thumb and second finger and holding said knob against rotation, presses upon the thumb piece 7' and moves the sleeve-connected arms 7 down, as shown in Figs. 1 and 6, thereby carrying the ribbon.

8 down in front/of the platen to lie between the paper sheets, and back of the index pointer 24, and main ribbon 25'Figs. v6 and 7.

In this position, it becomes functionally operative and is there stopped by the arm 7 resting on the bar 11 of the lever 9' and is v frictionally held against unintentional displacement by the lower spring tongue 13 of the controlling plate 12. v

If the second manifolding ribbon 5, in

addition to the first one; is required, the

thereby prolonged. I have, therefore, pro

vided for such a shift at each line spacing of the platen. This is effected bywthe cam 10 and the lever 9. When the platen is turned for line spacing the cam will suc-.

cessively lift and lower the lever 9 and this movement of the lever, through its connected controlling plate 12, will successively lift and lower the ribbon-carrying arms, and thereby shift the ribbons slightl up and down, and thus bring them throng out their width into the line of type impact.
